Embodiment 1

[0020] A preparation method of low-viscosity iron oxide yellow pigment, the steps are as follows:

[0021] (1) raw material preparation: prepare common synthetic iron oxide yellow powder;

[0022] (2) Ball milling: prepare the ball milling equipment, under the continuous strong vibration of the steel ball, according to the internal powder running track, move from top to both sides and move down to fully grind the iron oxide yellow powder;

[0023] (3) Ultra-fine crushing: the iron oxide yellow powder after ball milling is carried out ultra-fine crushing with a pulverizer, so that those cracks that have not yet been broken are completely broken under the action of high-speed shear force;

[0024] (4) Finished product: Detect the color and viscosity of the treated yellow iron oxide powder to obtain a finished product.

[0025] Step (2) The ball milling equipment is: mechanical power: 50kw, total amount of steel balls: 2300kg, there are ￠18㎜, ￠16㎜, ￠14㎜, ￠12㎜ steel balls in four...

Abstract

The invention discloses a preparation method of a low-viscosity ferric oxide yellow pigment. The preparation method of the low-viscosity ferric oxide yellow pigment comprises the following steps: (1) preparing the raw material which is common synthetic ferric oxide yellow powder; (2) ball milling, namely preparing a ball milling device and fully milling the ferric oxide yellow powder by moving a steel ball in a manner of circulating from top to two sides and bottom according the moving trajectory of the inner powder under continuous powerful vibration; (3) ultrafine grinding, namely ultrafine grinding the ball-milled ferric oxide yellow powder by using a grinding machine so as to completely break the unbroken cracks in the presence of high-speed shear force; and (4) preparing a finished product, namely detecting the color and the viscosity of the processed ferric oxide yellow powder to prepare the finished product.

Description

technical field [0001] The invention relates to a preparation method of iron oxide pigment, in particular to a preparation method of low-viscosity iron oxide yellow pigment. Background technique [0002] Iron oxide is the second largest inorganic pigment after titanium dioxide, and also the largest color inorganic pigment. Iron oxide pigments include four types of iron oxide red, yellow, black and brown based on iron oxide. 70% of iron oxide pigments are prepared by chemical synthesis method, which is called synthetic iron oxide. Synthetic iron oxide pigments have high synthesis purity, uniform particle size, neatness, easy control, non-toxic, and low price. They can be used in ink, plastic, Various fields such as coatings, rubber, ceramics, building materials, and papermaking. Because the quality level of the pigments prepared in our country is lower than that of the international ones, and the cost is high, the preparation process of iron oxide has always been concerned....
